Notice:Array to string conversion,该如何解决

function showPageV($id,$vnum)
{
	$this->pageModel->id=$id;
	$this->pageModel->get_entries(); 
        var_dump($vnum);
        print_r($this->pageModel->query->result_array());die();
        $this->smarty->assign($vnum,$this->pageModel->query->result_array());
        $this->smarty->assign('mainid','theDiv'.$this->p);
}
